How Parnell May Discover Who
Forged tho Letter-The Microscope
Useful for That Purpose-Faets
About This Valuable Instruments.
'Perhaps Parnell will demand that
the microscope be used on the forged
letter The London Times published this
week-the same way we detected tho
famous Morey letter." remarked Prof.
John Phin in the hearing of a Mail and
Ezpress reporter. Prof Phen is q
leading authority on microscopy. and
was the man who detected with a mi
croscope. the fraudulent forgery of Cen
Garfield's signature to the Morey let
ter. The talk led to the subject Of
microscopy and its recent development
here. The professor says that micro
scopic societies arc now a feature OF
nearly every Large city in the union.
The interest in the study has increased
many fold the past few years. and now
all classes of persons take the most ac-
tive interest in it, lawyers, merchants,
and clergymen. study rs zealously and
make as close research as physicians
and scientific men, to whom it is pro-
fessional matter. Some of the best stu
dents are amateurs, and the president
of the New York society is a clergy
man. This society has upward of one
hundred members and meets twice .
month. Often at these meetings eighty
to one hundred tables are prepared
each with microscope and novel SUBJ
ject for examination.
THE ladies, especially. are taking
great interest in the study" added the
professor, land they are wonderfully
adapted, b. both taste and delicacy OF
touch. for the work. Why. we have
in this country what Europe does not
have. a microscopic society composed
wholly of women. This is at the
Wesleyan Female college in Massa-
chusetts. 1t is, too. q very fourisbing
body. We have also, nowadays. pro-
fessional microscopic analysis. There
are probably twenty-five or thirty in
this city. They are kept busy examin.
ing into adulterations of food. and in
forgeries their work is most impor-
tant The fact is. as an instrument OF
research. the microscope is second to
none. There is hardly any department
of science in which student can hope
to reach eminence without familiar
ity W tn this instrument In chemistry
its services have been very important,
and in geology and mineralogy it has
opened up new fields of research,
which almost promise to revolutionize
these sciences. One of the most i'm
portant of recent changes brought
about in practical way by the micro
scope is in brewing. BY it a low form
of animal life has been discovered.
which rots the beer, and measures
have been taken to exclude this.
There are two mistakes made by be-
ginners in the study which should be
avoided. One is in supposing that it
is only by means of very expensive and
complicated instruments that any ything
of value can be accomplished. Now.
while it is certain that in some depart
ments of study none but the very best
microscopes are OF any value, it is
equally certain that n very wide range
of study and OF pract cal work can be
thoroughly cultivated by means of ap-
paratus Of very moderate cost and of
great implicitly of construction. The
great discoveries of Ehrenberg, which
at the most would not command $25.
The other mistake is of prec sely the
opposite kind 1t is not at all unusual
to meet persons who seem to think that
all tina. is necessary in order to become

and place objects under it. Truth lies
between these extremes. No progress
can be made without steady applica-
tion and persistent labor. but any per-
son of fair average ability and q mod
crate degree of perseverance can soon
learn to follow the beaten track, at
least, if not to branch out into oligi-
nal research.
"Whut are some of the most curious
facts you know about microscopy"
